SlRUP-PUMP.

SPECIFICATION forming part of Letters Patent No. 414,513, dated November5, 1889.

Application led June 19, 1889. Serial No. 314,781. (No model.)

the letters and iigures ot reference marked thereon.

This invention relates to certain new and useful improvements in pumpsdesigned more particularly as a Sirup-pump; and it has for its object toprovide a device of this charac-v ter which shall be efficient in useand simple in construction, providing for the alternate opening andclosing of the inlets and outlets, and preventing waste from drippingafter the required amount of liquid has been pumped.

The invention consists in the peculiar combinations an d' theconstruction, arrangement, and adaptation of parts, all as more fullyhereinafter described, shown in the drawings, and then particularlypointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figure 1 is a perspective View of myimproved pump. Fig. 2 is a longitudinal section through the same. Fig. 3is a cross-section on the line .ft of Fig. 2. Fig. at is a crosssectionon the line y y of Fig. 2. Fig. is a perspective view of the piston-headdetached.

Like letters of reference indicate like parts throughout the severalviews in which they occur.

Referring now to the details of the draw ings by letter, A designates acylinder of suitable size and material, open at one end a-nd at theother provided with external screwthreads a to receive the internalthreads of a detachable cap B. This cylinder is formed near itscappedend with a tapered external ly-threaded portion l), adapted to bescrewed into the cash, barrel, or other receptacle the liquid from whichit is designed to remove. Between this threaded portion and the cappedend of the cylinder is a discharge-spout c. This cylinder is providedupon diametricallyopposite sides with longitudinal slots d, which arethe inlet-ports into the pump.

C is an inner cylinderor tube of such asize as to work snugly within thecylinder A, and is also provided upon diametrically-opposite sides withlongitudinal slots e, of the same size in width as those in the cylinderA, and adapted to register therewith at intervals, as will hereinafterappear. Atits open end this inner tube or cylinder is formed with anotch f, the end walls of which are adapted to cngage with a stop-pingon the inner wall of the outer cylinder, as shown in Fig. 2, to limitthe revolution of the inner tube. The other end of the inner tube has ahead 71- at a short distance from the end, leaving a chamber fi beyondsaid head, andy` is a boss extending through said chamber and through ahole in the cap B. The ou ter end of this boss is screw threaded andreceives a nutt, as shown. D is apiston or pump rod passed through thisboss and nut, and at its inner end carries a piston or plunger head E,formed of the disk l., preferably of metal, and the leather orequivalent disk n. A transverse piece m is secured across the faceV ofthe leather disl-z, and pro jects beyond the same, so as to extendthrough the slots in the inner tube, the leather of the disk also beingextended to correspond with the said cross-piece. The piston or pump rodis sorewthreaded through this piece and through the metal and leatherdisks, and upon the other side is provided with a nut o, all so arrangedthat by turning the handle p to the piston-rod the inner tube will begiven a half-s revolution, for a purpose hereinafter described.

The operation is as follows: lli-'ith the parts constructed and arrangedas above set forth and shown the device is screwed into the barrel bymeans of the threaded portion h, and the inner tube turned so as to makeits slots register with those in the outer cylinder. The handle is thenturned so as to make one of the slots in the inncrtube register with thedischarge. Then by pulling out the piston, the piston will bring out theliquid to the disa chargespout. By turning the handle of the pistonrodthe inner tube can be given a half- IOO revolution when desired to closerthe inlet-- n the piston, thus opening and closing the inlets `andoutlets alternately. By this cbnstruction the pump is arranged Withinthe barrel, where it acts on the sirup Without Waiting for it to Vrunlengthwise through a tube as heretofore, thus saving time and patienceand producing a device which is speedy, certain, and positive in itsaction, working as readily in winter as in summer, with thick as withthin liquids.

I contemplate employing in connection with the mechanism above describeda measuring or registering ,device whereby the amount of liquid pumpedmay be readily ascertained, but have not shown such contrivance in thedrawings. Preferably, however, I shall employa disk revolving on thenuton the boss or on the boss itself, said disk being properly numberedin a manner common in such devices. y

In order to prevent the waste usually attending devices of this kind,occasioned by the dripping of the liquid after the desired amount hasbeen obtained, I pivot, as at q, between lugs or ears ron the piston-roda lever t, having a handle u, and its other end adapted to engage a stopo on the cap of the outer cylinder. Vhen the piston rod is grasped toactuate the same, the hand grasps the handle of the lever; but when thehandle of the piston-rod is let free the freeend of the lever engagesthe stop and holds the parts in their proper position. This holds thetubes with their slots not coincident, so that no liquid can enter theinner tube, and consequently none can discharge therefrom.

What I claim as new isl. In a pump of the character described, thecombination, with the outer cylinder pro- The inner tube can be turnedbackv vided with diametrically-opposite longitudinal slots, of the innertube provided with diametrically opposite longitudinal slots, the solidpiston-head having portions extending through the slots of the innertube, and its rod arranged Within the inner tubel and adapted to have ahalf-revolution therewith, substantially as shown and described.

2. The combination, with the outer, cylinder having longitudinal slotsand the inner tube having longitudinal slots, of the piston within theinner tube and having portions extending through the slots of the innertube, and the piston-rod passed through the piston and provided upon itsinner end with a nut, said piston-rod being free to make ahalf-revolution and to turn the inner tube, substantially as described.

3. The combination, with the inner and outer slotted tubes, of thevsolidpiston-head within the inner tube, and consisting of a metal disk, aleather disk and a transverse piece extending beyond the metal disk intothe slots of the inner tube, and a piston-rod connected with thepiston-head, substantially as shown and described.

4. The combination, with the outer cylinder form ed with a taperedextern ally-threaded portion b, of the inner slotted tube, the pistonwithin the inner tubeand having portions extending through the slots ofthe inner tube, the piston-rod connected with the piston and adapted togive the inner tube and piston a half-revolution, and the locking-leverpivoted to the piston-rod and adapted to engage a stop on the outercylinder, substantially as shown and described.

In testimony that I claim the above I have hereunto subscribed my namein presence of two witnesses.
